Digestion of Protein: Microbes
Milk the resource for all it's worth. Young biologists perform assay techniques to test the digestion of protein. They place bacterial samples, fungal samples, trypsin solution, and distilled water on a milk-agar plate to see the effects...
Cornell University
Classification
Explore the scientific method of classification. An interactive activity asks learners to create a classification system for a group of objects and develop a flow chart to communicate their systems. In addition, individuals use a...
Cornell University
Electroplating
Silver pennies and copper nickels are made possible by applying some chemistry. Learners use electrolysis to coat a penny with zinc sulfate and a nickel with copper sulfate. Their investigation builds an understanding of electroplating...

Discovering Enzymes
Explore the function of enzymes through a series of lab investigations. Learners use household enzymes such as hydrogen peroxide to model the role of enzymes. The enzymes break down proteins with and without a catalyst.
Cornell University
Friction
Friction and gravity are always at odds! Learners complete a set of activities to explore the relationship between friction and gravity. Groups make conclusions about the factors that affect the amount and type of friction between surfaces.
Cornell University
Sound Off!
Time to witness the effects of sound. Learners analyze different materials to determine their abilities to absorb sound waves. They use free software to monitor the amplitude of the waves to verify results.
